Adobe Systems is bringing its Flash-based AIR runtime to mobile devices, with Google's Android the first potential host. Adobe will show a preview running on Motorola's Droid and Milestone phones at the Mobile World Congress today in Barcelona, Spain, with general availability promised later this year. AIR combines Flash with components such as a local SQL database, running outside the web browser and is used by the BBC iPlayer Desktop and many Twitter clients such as Tweetdeck. So far, it's not been available on smartphones.
